Information-Theoretic Performance Limitations of Feedback Control: Underlying Entropic Laws and Generic Bounds
Song Fang, Quanyan Zhu
In this paper, we utilize information theory to study the fundamental performance limitations of generic feedback systems, where both the controller and the plant may be any causal…
Relativistic Control: Feedback Control of Relativistic Dynamics
Song Fang, Quanyan Zhu
Strictly speaking, Newton's second law of motion is only an approximation of the so-called relativistic dynamics, i.e., Einstein's modification of the second law based on his theor…
Fundamental Limitations in Sequential Prediction and Recursive Algorithms: Bounds via an Entropic Analysis
Song Fang, Quanyan Zhu
In this paper, we obtain fundamental bounds in sequential prediction and recursive algorithms via an entropic analysis. Both classes of problems are examined by i…
Generic Bounds on the Maximum Deviations in Sequential Prediction: An Information-Theoretic Analysis
Song Fang, Quanyan Zhu
In this paper, we derive generic bounds on the maximum deviations in prediction errors for sequential prediction via an information-theoretic approach. The fundamental bounds are s…
Two-Way Coding and Attack Decoupling in Control Systems Under Injection Attacks
Song Fang, Karl Henrik Johansson, Mikael Skoglund +2
In this paper, we introduce the concept of two-way coding, which originates in communication theory characterizing coding schemes for two-way channels, into control theory, particu…
Generic Variance Bounds on Estimation and Prediction Errors in Time Series Analysis: An Entropy Perspective
Song Fang, Mikael Skoglund, Karl Henrik Johansson +2
In this paper, we obtain generic bounds on the variances of estimation and prediction errors in time series analysis via an information-theoretic approach. It is seen in general th…
Two-Way Coding in Control Systems Under Injection Attacks: From Attack Detection to Attack Correction
Song Fang, Karl Henrik Johansson, Mikael Skoglund +2
In this paper, we introduce the method of two-way coding, a concept originating in communication theory characterizing coding schemes for two-way channels, into (networked) feedbac…
